Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint, so safety is covered. The description adds two useful facts beyond them: the response is 'redacted' and it only applies to an 'identity-owned' intent, implying ownership scoping. It says nothing about freshness, eventual consistency of finality state, or rate limits, so it stops short of rich behavioral context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
